Student Summaries:
The main points of section 2-1: Real numbers were being able to graph sets of numbers on a number line and to evaluate expressions with absolute value. Another key point was what real numbers actually were. When graphing with real numbers you use shaded lines instead of dots.When there is a negative sign in front of an absolute value box then it is negative. When graphing sets of numbers and integers you use dots. by Jamie L. and Jared K.

this summary I am going to talk about the order of operations. The phrase that helps me is please excuse my dear aunt sally. Addition and subtraction are on the same level, also multiplication and division are on the same level this means that you have to do what ever comes first. You have to go from left to right. - Isaac H.
In section 2-2 we learned about using order of operations in expressions and which operation too use first. Too remember the order of operations we used the phrase "my dear aunt sally", this method helps you by deciding which operation comes first. -Paul R.
In section 2-3 we learned about writting variable expressions. In the lesson you learned how to write a variable expression to represent a word phrase. For example 3 + x would be three increased by a number (a number representing x). We also learned how to write a word phrase to represent a variable expression. For example six times a number would be 6a (a representing a number.) ~Alyssa M.~
For 2-3 the goal was to learn how to write variable expressions into word phrases & vis versa. Being able to phrase expressions into words can help a person break down a problem into pieces. Basically the way you turn an expression into a word phrase is by saying the expression & just placing it into words instead of numbers & variables.

In lesson 2-4 we learned to how to subtract and add variable expressions. By simplify adding the terms together first and than finish working the problem out. Samantha R.
This section was all about Terms and variable expressions. We learned how to combine like terms. We learned how to add and subtract variable expressions. - Tyler P.
Student Summaries:
Chapter 2-5 is Multiplying and Dividing Variable Expressions. You simlifiy and evaluate the expressions until you can't. You'd have to so some order of operations to start out with. It's hard to explain but it's pretty easy to accomplish. You would use the distribution property.
For an example:
4(m + 7)
= 4m+28
-Sabrina O.
2-5 was about multiplying and dividing expresions. we did all kinds of pratice and stuff for it we took tests on it. it was a very good lesson what you do is multiply the expresions and you use letters for the varibles. - Tony Y.
Student Summaries:
We learned how to use the order of operations again. Also now we heard to simplify variable expressions. - Patrick E.
Section 2-6 is learning how to add, subtract, divide, and simplify all together. There is only one term in this section and that is the order of operations (G,P,E,M,D,A,S,). -Alexis H.
2-7/2-8: Properties of Exponents and Zero and Negative Exponents
Student Summaries: In this lesson we learned how to evaluate variable expressions, write numbers using zero and negative integers as exponents, and how to write numbers in scientific notation. -Cassi K. & Katlyn K.
Student Summaries: In this lesson 2-9; We learned about finding a pattern to find answers to questions that you need to use a pattern to solve. For example start with 5 and add 3 each time till you get to 20 ..it would be 5,8,11,14,17,20. That would be an example of an easy pattern. Some questions are harder to answer and you can also find a pattern to solve them.
-Alissa D.
we learned how to find a pattern when you need to find an answer to a problem where you need a pattern to solve it. an example would be you have 10 and you add 10 till you get to 200 the answers would be 20,30,40,50,60,7080,90,100,110,120,130,140,150,160,170,180,190,200. that is an example. some are harder than others
